LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 257,407, dated May 2,1882.

Application filed Fcbruary15, 1882. (No model.)

To all whom it may concern Be it known that I, CHRISTOPHER Srocn- MANN,a citizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented new and useful Improvementsin Lamp-Burners, of which the following is a specification.

' Thisinvention is especially adapted to Argand burners, but also partlyto burners of other forms; and it has for its object to produce apacking for a wick-raising rod upon the side of the burner which shallbe impervious to oil and prevent leakage around the rod without unduefriction also, in Argand burners to produce an attachment forconcentrating the wick at its burning-point, and thereby to permit theenlargement of the outer or main tube, which facilitates theintroduction of the wick, and to utilize such attachment for catchingthe cinders that drop from the wick.

This invention is illustrated in the accompanying drawings, in whichFigure 1 represents a longitudinal central section. Fig. 2 is a sideview, omitting the chimney-holder. Fig. 3 is a cross-section on the line.00 m, Fig. 1. Fig. 4 shows the packing for the wick-raising rod on anenlarged scale. Figs. 5, 6, and 7 are detail views of parts.

Similar lettersindicate corresponding parts.

The letter A designates the outer or main tube, and B the wick-tube, ofan Argand burner.

0 indicates the wick-earrier, fitted on the wick-tube; and D, thewick-raising rod, carrying at its inner end a pinion, a, which isadapted to engage arack, t, upon the wickcarrier and cooperate with suchrack for adjusting the carrier. The wick-raisin g rod D passes through astufiing-box, s, which is secured to the side of the main tube A, inthis example by being screwed into a suitable hole therein so that it isdetachable, thus allowing the removal of the pinion together with therod. The stuffing-box sis formed with an annular recess, 0', openingoutward and surrounding the wick-raising rod D,for the reception of afollower, E, and into the stufing-box is fitted a packing-sleeve, g,which is composed ofhard rubber, and embraces the wick-raising rod,while it is tapered toward the outer end, where it projectsinto or pastthe inner end of the boxrecess. The side of the box-recess r isscrewthreaded, and the follower E is secured therein by that means, thefollower being provided with a corresponding thread. This follower E ismade annular in shape to surround the wick-raising rod D, and the boreor inner surface thereof is flared toward its inner end, as clearly,shown, so that when the follower is screwed into place it engages thetapering outer end of the sleeve q and compresses the latter upon thewick-raising rod. In this manner the wick-raising rod is packed in aneffective manner, while, owingto the nature ofthe material composing thesleeve, it is not liable to exert an undue or obstructive friction uponthe rod. I would remark in this connection that I have found byexperiment that hard rubber is the only packing material which isimpervious to oil, and which thus is adapted to oil-lamps for thepurpose named. A hard-rubber packing, 0, also is preferably applied tothe stuffing-box s where it impinges against the burner.

Into the main tube Ais fitted a ring, F, which rests on the upper end ofthe tube by means of a shoulder, 11, formed thereon,and the innerdiameter of which is larger than the outer diameter of the wick-tube B,leaving a space between the ring and such tube approximately equal tothe thickness of the wick. The width of the ring F, moreover, is suchthat when it is putinto place the upper edge thereof is approximatelyeven with the corresponding edge of the wick tube. This ring F serves toconcentrate the wick at the burning-point,and thus allows the main tubeA, which heretofore accomplished this purpose, to be made oflargediameter, the effect of which is to facilitate the introduction of thewick into the burner.

In the top of the concentrating-ring F is formed a groove, n, whichopens upward and forms a receptacle for the cinders that may drop fromthe wick as it is consumed. In or dinary burners these cinders areliable to collect in the chimney-gallery and clog up its per forations,thus impeding the draft of air, besides soiling the article, whereas bythe groove 12 this is obviated.

The wick G is formed with an opening, l, (best seen in Fig. 7,) whichextends upward from thelower end thereof, and is of sufficient width toclear the rack 15 and pinion-a. This opening I thus adapts the wick tobe fastened to or upon its carrier 0 in such a manner as to dependtherefronnas indicated in Fig. 1, without interfering with the operationof the rack and pinion, and by this means the wick is caused to remainimmersed in the oil when in use for a long. period of time as comparedwith a wick terminating at the lower edge of the carrier, as heretofore,and the advantage thereby gained is that the wick requires theleastfrequentrenewal, which is a desideratum.

To the main tube A is fixed, as by solder, the chimney-gallery H, whichis perforated in the usual manner, and constructed with an annularrecess, 70, opening upward,.into which is fitted the lower edge of thechimney-holder I, the latter being left detached, whereby a simple andefficient connection of the holder is obtained,and one which allows theremoval of the holder, together with the chimney, asin lighting thelamp. The inner wall, 7a, of the gallery-recess is higher thanitsouterwall, and is arranged to bind the chimney-holder I, thus improving itsconnection with the gallery.

The chimney-holder I consists of the cone 1, havinga shoulder, j, whichforms a rest for the base or lower end of the chimney, combinedwith arim, I, formed with the usual chimney-holding springs.

The wick-rod D is'turned by an ordinary milled head, D, and the rack tis guided in a channel, t, having a slot, t which receives in it a pin,t on the rack, so as to regulate the movement of the latter.

I am aware that itis not broadly new to arrange a ring in the upper endof a wick-tube to form a nozzle for the wick; also, that it is not newto attach to the upper end of a wick- -tube an outwardly-projectingflange forming a recess around the wick-tube adjacent to the wick-tube;butsuch features, broadly, do not constitute my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore set forth, with theouter or main tube and wick-raising rod, of the stuffing-box having anannular recess opening outward and surrounding the rod, theoutwardly-tapering hard-rubber packing-sleeve embracing the rod Withinthe stuffing-box, and the follower screwing into the box-recess andhaving its bore flared to engage the tapering outer end ofthepacking-sleeve, for the purpose specified.

2. The combination, substantially as hereinbeforeset forth, with themain .tube and wicktube, of the wick-concentrating ring fitted into andresting upon the upper end of the main tube and formed with a grooveopening up ward for catching cinders, as specified.

3. In an Argand burner, thegallery .H, secured to the main tube andprovided with an annularrecess, is, formed by two vertical walls,

the inner one, 7t, of which ishigher than the 'outer one, as described,in combination with the chimney-holder I I, detachably arranged in theannular recess of the gallery, and against which the inner wall, 70,binds, substantially as and forthe purpose described. I

In testimony whereof I have hereunto set 7 my hand and seal in thepresence of two subscribing witnesses.
